25 Mounting 9 Prerequisites 91 Area of installation The installation area must fulfil the following requirements: Closed, dry, well ventilated room No purpose-built room (e g heating or wet room) Because of the amount of noise generated, we recommend that the unit be installed in an adjoining room Set up the unit on a flat, horizontal and stable surface (take the weight of the unit into account) Set up the unit so that the model identification plate can be easily read and that the unit is easily accessible to personnel for operation and maintenance Set up the unit so that the socket outlet to which the unit is connected is easily accessible Set up the unit as near to the compressed air pipeline as possible (length of hose supplied is 3 m) Leave sufficient distance from any wall (approx 20 cm) Comply with the environmental conditions "6 Technical data of compressor stations" The air is filtered during the intake The particular features of the air are unaffected The source of the air taken in should be free of any harmful substances (eg do not draw in air from a basement garage or from directly next to a suction machine) 40 C NOTICE Risk of overheating due to insufficient ventilation The unit gives off heat This can lead to damage due to high temperatures and/ or to a reduction in the service life of the compressor unit Do not cover the unit Install auxiliary ventilation for the room where ambient temperatures exceed 40 C L V001 23

26 Mounting 10 Transport WARNING Explosion of pressure tank and pressure hoses Only store and transport the pressure tank and pressure hoses in a completely vented condition Protect the unit from moisture, dirt and extreme temperatures during transport (see Ambient conditions) Only transport the unit when the condensate collecting chamber is empty ("151 Shut down the unit") Always transport the unit in an upright state Only transport the unit using the intended carrying handles 11 Operation 111 Remove the transport protection For safe transport, the unit is securely protected with foam rubber padding protectors and a plastic transport strap Cut the plastic transport strap and remove Remove the foam rubber padding 112 Set up compressed air connection The flexible pressure hose supplied between the plumbing system and the compressor prevents the transmission of vibration and reduces noise This ensures safe operation Connect the connecting sleeve (premounted on the pressure hose) to the quick release coupling Measure the required length of the pressure hose and shorten if necessary Slide the second hose nozzle in place and secure with a hose clip Connect the connecting sleeve on the pressure hose to the compressed air line L V001

27 114 Electrical connection Mounting Safety for the electrical connection The unit may only be connected to a correctly installed socket outlet Make sure the connection lines to the unit are not subject to any mechanical tension Before initial start-up, check the supply voltage with the voltage information on the model identification plate (see also "4 Technical Data") Establish electrical connection 113 Place the collector tray underneath During operation, condensate on the unit is constantly separated and automatically drained In order to prevent water damage due to drained condensate, it is collected in the collector tray DANGER Electric shock caused by defective mains cable Mains cable must not come into contact with the hot surfaces of the unit Plug the female connector of the power cord into the corresponding male connector at the pressure switch As an option, the condensate can be removed using a hose connected to the waste water system Heed the national regulations for waste water systems Place a collector tray under the condensate separator or the membrane drying unit (depending on type) L V001 25

28 Mounting Secure the female connector using the cable tie provided Switch on the unit at the pressure switch by rotating this switch to the "I" position Plug the mains power connector into an earthed power socket 115 Check the motor protection switch For compressors that must be operated at V, the motor protection switch must be checked and adjusted if there are deviations The motor protection switch is structurally combined with the pressure switch This has been set to the recommended setting in the factory (see "6 Technical data of compressor stations") Compressors that must be operated with 230 V, have a winding protector which cannot be set instead of a motor protection switch Measure the rated current (value just before reaching the cut off pressure) Result: If the read value deviates from the recommended setting, the motor protection switch must be set (see "6 Technical data of compressor stations") 116 Checking the initial pressure/ cut off pressure The initial pressure/cut off pressure is preset at the factory Check the setting at start-up Switch on the unit at the pressure switch by rotating this to the "I AUTO" position Read off the cut off pressure at the pressure gauge Drain air from the pressure tank (e g on the condensate drain valve) until the unit starts and then close again Read the pressure when switching on the unit Result: If the values read deviate from the values preset at the factory, adjust the pressure switch to the factory settings L V001

29 Mounting 7,8 bar (0,78 MPa) 12 bar 117 Check safety valve settings The function of the safety valve must be checked when the unit is started up and at regular intervals The safety valve setting is set to 10 bar (1 hpa), checked and stamped as approved in the factory DANGER Explosion of the pressure tank and pressure hoses Do not change the safety valve settings Switch on the unit at the pressure switch and fill the pressure tank to the cut off pressure 118 Draining the condensate Temperature changes during transport may cause condensate to accumulate in the pressure receiver The condensate can only be drained from the pressure receiver when it is pressurised Switch on the device at the pressure switch and wait until the cut-out pressure has been reached Close the condensate drain valve once the condensed water has run off completely WARNING Damage to the safety valve Explosion of pressure tank and pressure hoses due to defective safety valve Do not use the safety valve to vent the pressure tank To open, rotate the screw of the safety valve to the left until the valve begins to blow off Only allow the safety valve to blow for a short period Now turn the screw to the right as far as it go to close the valve The valve must now be closed again L V001 27

30 Mounting 12 Setting possibilities 121 Pressure switch setting DANGER Bare parts subject to electrical current Electric shock due to parts under electrical current Unplug the unit at the socket outlet Use insulated tools Do not come into contact with live parts The cut off pressure must be at least 05 bar (0,05 hpa) below the maximum pressure of the safety valve setting of 10 bar (1 hpa) Otherwise the safety valve can open too early, the cut off pressure will not be obtained and the compressor will run continuously The maximum permitted pressure is marked by a red line on the pressure gauge provided Setting at 230 V If the read values deviate from the factory settings or if other settings are required, the cut off pressure of the compressor can be adjusted using the setting screw on the pressure switch The pressure difference Δp cannot be altered Lift off the pressure switch unit cover Set the cut off pressure p using the setting screw The arrow direction "+" means the cut off pressure is increased and the arrow direction "-" means the cut off pressure is decreased Setting at V If the values read off deviate from the factory settings or where other settings are required, the compressor cut off pressure can be altered by adjusting the setting screw on the pressure switch unit The switch-on pressure can then be adjusted using pressure difference Δp Lift off the pressure switch unit cover Adjust the cut off pressure P at the setting screw The "+" arrow direction increases the cut off pressure and the "-" arrow direction decreases the cut off pressure Pressure difference p is also influenced by this adjustment Adjust the switch-on pressure using the pressure difference p at the setting screw The "+" arrow direction increases the pressure difference and the "-" arrow direction decreases it 0 bar 16 P L V001
